Rheological properties of suspensions containing cross-linked starch nanoparticles prepared by spray and vacuum freeze drying methods

► Starch nanoparticles were produced through spray drying and vacuum freeze drying. ► Rheological behavior of suspensions containing these two types StNPs was investigated. ► Suspensions contain spray dried StNPs showed lower viscosity within shear range tested. ► Suspensions contain freeze dried StNPs showed stronger shear thinning and thixotropic. ► Suspensions containing freeze dried starch StNPs showed stronger elastic structure.
